cation Novem- 1 Claim. (Cl. 174-44) This invention relates to improved electrical wiring systems, and particularly to improved conductor carrying units arranged for seriatim interconnection to aiiord a continuous electrical circuit.

The present application is a division of my pending application Serial No. 704,189, entitled "Electricity conductor units," and now U. S. Patent No. 2,218,545, dated October 22, 1940.

It is an object of the present invention to provide run" conductor units and connector" conductor units for seriatim interconnection, the said run" and connector units having means affording a complete insulation of the conductor means or such interconnected units in the zone of interconnection thereof, to eliminate danger of accidental short circuiting oi the conductor means.

It is a further object of the present invention to .provide electricity conductor units for seriatim interconnection, said units having socketed end portions of which the walls are integral with the body portion and form a continuous enclosure coextensive with the external faces of the body portion of the units. Such socketed end portions receive, and completely envelop, male end portions of the therewith interconnected conductor units.

In the accompanying drawing, of which the figures are perspective representations:

Fig. 1 shows an outlet-provided connector unit having a male connection end and a female connection end for seriatim interconnection with electricity conductor run units;

Fig. 2 illustrates a portion of an electric circuit, showing an angle connector unit embodying female connection ends and a therewith interconiected "run unit having male connection end aortions mechanically interconnecting with said cOnnector unit; and

Fig. 3 illustrates a T connector unit embodyng the present invention.

Referring to the drawing for a more detailed escription of the invention, the electric circuit which is mechanically in- :rconnected a run unit A8. A second run unit JOi; shown) may be inserted in the vertically disused socketed end. Desirably, the body I22 of connector unit A! 1d the body 63 of run unit A8 is wholly of eleclcal insulation material. The respective body iltlOllS incorporate any desired plurality of eleclcity conductors. Connector units A! may be provided at either both ends, with socket facilities for male and 5 the conductor units from any exposed face of the interconnected wiring system.

The sockets I23, I23

cally conducting material, the terminal openings of such sockets being flush with the base wall of sockets I23.

The run units, typified by A8 of Fig. 2, comprise a body 63, desirably wholly of electrical insulation material and end portion I24 so dimensioned that it engages snugly with the socket I23 of conductor unit A1. Desirably such male connection portions are symmetrical with the major axes of the body 63 of the run unit, and the lateral faces of such male connection portions are, therefore. oilset with respect to the corresponding lateral faces of the body portion, the degree of such offset being substantially equal to the thickness of said female socket walls. As shown in Fig. 2, the connector and run units are preferably of identical contour and cross sectional area, thus ail'ording an interconnection which is without noticeable break or oil'set, and achieving visual continuity of the interconnected units.

Pins are arranged for a snug frictional engagement with the inner wall of the sockets 51, such frictional engagement 2 for, such snug nt being rendered additionally efiective for mechanical interengagement by'the relatively great area of engagement of the extension portion I with its associated socket I23.

The embodiment of Figure 1 illustrates an outlet-provided connector unit i4 I the outlets thereof being designated I18, I". Such connector unit may have a socketed end portion I11, similar to that described with-respect to Fig. 2, embodying electrical conductor sockets I1 terminating at the base or such socket portions as shown. The opposite end of such conductor unit may be provided with a male extension portion llla and projecting conductors 55, for interconnection with the socketed portion of a second connector unit, or with the socket portion of a run unit, as illustrated, such run unit being provided with socketed conductors. as will be understood.

Fig. 3 indicates a T unit by means of which a vertical branch circuit maybe derived from a run circuit. Such T unit, designated I25, may have two of its ends provided with sockets, such as I26, I28, with an end provided with a male connection extension, designated Ilia, for connection with the socketed end of a run unit, as described with respect to Fig. 1.

Whereas I have described my invention by reference to specific forms-thereof, it will be under stood that many changes and modifications may be made without departing from the spirit of the invention.

I claim: An electricity conductor unit adapted iormale and female seriatim interconnection with other conductor units having substantially identical racial configuration and dimension and substantially identical end configurations, comprising a body of rigid insulation material having iixed therein a plurality of electricity conductors arranged in mutually spaced insulated relationship and terminating at .the ends of said body in electricity conductor means adapted for electrical tion disposed symmetrically with respect lygonal extension being inwardly oflset with reconnection with electricity conductors of adjacent units, said body of rigid insulation material having at one end a deep polygonal socket formato the body 0t the unit and characterized by external walls which are co-planar continuations of the walls of the mainbody oi the unit, and at another end with a polygonal extension portion symmetrical with the body of the unit and having an external configuration matching the configuration oi the socket and a length 01 extension equal to the depth of the socket, the lateral walls of said pospect to the walls of the main body of the unit to an extent equal to the thickness of the walls of the socketed end, and each of said extension walls being in the plane of the corresponding wall 01' the socketed end whereby the surfaces of the polygonal extension of one unit will be in contact with the socket walls of an adjacent unit at all relative positions of insertion of the extension into said socket.
